Abstract:
The main problem for design an energy efficient lighting systems of road tunnels
is the choice of the maximum value for the luminance L20 in the access zone. Method and computer program for calculating the annual chart of luminance L20 are presented in this paper. This chart is used for calculating the frequency and cumulative frequency distribution of L20 over the whole year. The safe maximum value for the luminance of the access zone can be evaluated directly from the cumulative frequency distribution for any percentage taken into account. A verification of the results is made by measurements made in 4 tunnels in Germany
